Ubuntu – The kernel is not the latest for 14.04

14.04aptkernelupgrade

My kernel is currently

Linux scv 3.13.0-34-generic #60-Ubuntu SMP Wed Aug 13 15:45:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

But I know it should be

3.13.0-45-generic #74

Why is it not updated by default on my pc upon execution of

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

Any idea? How can I fix this?


EDIT:

executing

ema@scv:~$ cat /etc/issue
Ubuntu 14.04.2 LTS \n \l

reports 14.04.2 apparently…


EDIT2:

on my other computer, with a fresher install of Ubuntu 14.04, I got 3.13.0-45-generic #74

Best Answer

Apparently I didn't have the meta package linux-generic installed... A simple

sudo apt-get install linux-generic && sudo apt-get install --reinstall nvidia-346

Did the trick!
Amazing, didn't think I somehow managed to remove that meta-package...

Now I got

ema@scv:~$ uname -a
Linux scv 3.13.0-46-generic #75-Ubuntu SMP Tue Feb 10 15:24:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Result!
